AI agent verification API for autonomous workflows

Agent Verifier is an AI automation guardrail and agent output validation API. It gives AI agents, MCP tools, n8n workflows, lead-generation bots, and SaaS automations a machine-readable checkpoint before they act on generated data.

Use the OpenAPI schema to connect agent frameworks and developer tools directly: /openapi.json. AI agents can also read the compact discovery file at /llms.txt.

Verify generated JSON

Catch malformed records, missing fields, schema mismatches, and unusable tool-call payloads.

Check URLs and emails

Confirm reachability, HTTPS, expected page text, email syntax, and optional DNS hints.

Score agent output

Require terms, forbid risky phrases, enforce JSON/plaintext formats, and return machine decisions.

First monetizable use case: lead-gen agent guardrail

Agent finds a lead → Agent Verifier checks JSON, company URL, email, and required fields → only safe records get written to CRM. Uncertain records go to human review. Failed records get regenerated or discarded.
